REEL AND HANGER FOR BOX-STRAPPING.

Application filed June 29, 1912.

T (ZZZ whom it may concern Be it known that I, GEORGE C. D. MILLER, a citizen of the United States, residing in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Feel and Hanger for Box-Strapping, of which the following is a specification.

This invenion is a reel and hanger on which box strapping may be coiled for shipment and uncoiled for use, and the object of the invention is to construct a device of the character specified out of sheet metal in a simple and economical manner, and to produce a device which is light and compact in construction and efficient'in operation.

lVith the specified objects in view, the invention embodies a sheet metal support or hanger in which is securely journaled a spool or bobbin of such construction that it mav be readily stamped from sheet metal.

The preferred construction of the spool or bobbin is a centrally perforated fiat disk provided near its periphery with short substantially radial slits with the portions between the slits bent alternately in opposite directions and perpendicular to the plane of the disk, thereby forming the rim of the spool.

T he hanger is preferably made of a continuous piece of strap iron the ends of which are doubled so as to produce two loops, the said ends overlapping, and, in conjunction with the opposing side of the hanger, serving to form, by means of one expedient or another, a support or journal for the spool. The said ends and side memher are bent inwardly to form cheeks between which the spool disk is positioned.

The inwardly bent portions of the hanger,-

i. e. the cheeks, bear against the disk portion of the spool for the purpose of retaining said spool in a centrally disposed position within the hanger and preclude it from lateral displacement.

I have several ways for securing the spool in a rotatable position within the hanger. The preferred method, however, consists in employment of a rivet, preferably tubular, extending through alined perforations in the cheek pieces and disk of the spool, respectively, the ends of the rivet being then upset so as to retain it from dis placement.

Fig. 10 is a cross section on the line 101O of Fig. 2). Fig. 11 is a cross section of the spool employed in the construction of Figs. 9 and 10. Fig. 12 is a perspective view of the hanger partly broken away, with the spool omitted, and showing the relation of the cheek pieces between which the spool is retained when in operative position within the holder. Fig. 13 isa detail perspective view of a tubular rivet adapted for use in the construction of Figs. 9 and 10.

Referring more particularly to Figs. 1, 2, 3, 4 and 5, the hanger or reel embodies two main elements, a frame or housing A and a spool or bobbin B, said spool being positioned within the frame or housing, intermediate the ends thereof, and mounted for free rotation within said frame or housin In a preferred form of construction, the frame is composed of strip metal and the spool is composed of sheet metal.

Frame or housing A is made from a strip or length of metal substantially uniform in width, said length of strip metal being cut from a piece of bar metal, and thereafter doubled upon itself and manipulated in a particular way to produce the frame or housing in accordance with this invention. As shown more clearly in Fig. 2, the strip or length of sheet metal is doubled or folded to produce parallel sides 1, 5 and loops at", a at the respective end portions of the frame or housing, the two free ends of the length of metal being positioned in overlapping re lation when the parts are properly assembled, as shown in Fig. 4. Proceeding now to a more detailed description of the sheet metal frame, the side 1 is bent inwardly at 2, 3 intermediatethe ends so as to produce a cheek piece 4 between the inclined inwardly bent portions 2, 3, said bent portions 2, 3, 4: constituting one cheek member on the side 1 of the frame. After bending the length of metal at a a the two free ends are brought into parallel relation to the side 1 so as to produce the side 5, the

' two free ends f the metal are then tent inwardly at- 6, 7' and said free ends are then brought into overlapping relation to produce a cheek member 8, the latter being parallel' to the cheek member 4. The cheek members 4, 8 are positioned quite closely togetherand parallel to each other, the distance between the cheek members i, 8 being" very much less than the distance between 'guides for'said spool, thereby precluding displacement or. ,movement of the spool within the frame. The free overlapping end portions of said member 5 are provided with perforations 9 adapted to register or aline with each other. The other side member 1 has its cheek piece cut or slotted at 10 so as to produce tongues 11, the metal being slotted lengthwise of the inwardly extending portions 2, 3 and the cheek piece 4, as shown more particularly in Fig. 5, and the tongues 11 being bent inwardly with respect to the member so as to pass through the alined apertures 9 in the cheek piece 8, after which the free ends of said t ngues 11 are bent outwardlyat 12, see Figs. 3 and 4:, whereby the tongues on one cheek piece 4 are adapted to secure the free ends of the sheet metal band in predetermined relation.

7 The spool or bobbin is preferably stamped from a single piece of sheet metal, said spool consisting of a disk 2) and a rim 6. \Vhen the disk is stamped from a piece ofv sheet metal a series of radial slits or incisions are formed in the periphery of the disk, and

thereafter the slitted edge of the disk is bent I alternately in opposite directions so as to produce the rim, that is to say, one piece of the sheet metal disk 1s bent in one direction cal, although not continuous, and upon this wide substantially cylindrical surface of the spool. is adapted to he coiled a box strapping or other material which is to be housed or contained within the hanger. The disk is provided with a central aperture, and through this aperture extends the tonguesll when the parts are properly assembled, said tongues 11 constituting a journal on which the spool is rctatably mounted. The spoolis positioned between the side members 1, 5 of frame A, and it is supported between the cheek pieces 4, 8 and upon the journal afforded' by the tongues 11. The wide rimb of the spool is positioned within the wide space between the parallel side members 1, 5 so thatthe spoolwill rotate freely within the frame or housin' but sidewise' move- C31 ment of the spool is precluded by cheek pieces 4, 8 which arepositioned to contact with the respective sides of disk 7) forming apart of the spool.

By reference to Figs. 2 and t it will be noted that the inwardly extending members 2, 3 and 6, 7 on the parallel side members 1, 5 extend inwardly toward the disk of the spool, within the wide rim thereof, and thus the cheek pieces a 8 are positioned in very close relation to the respective faces of the disk 6, whereby the cheek pieces serve as guides to the spool in preventing any sidewise movement of said spool within the hanger.

The operation is as follows: The box strapping is coiled around the rim of the spool before the latter is placed within the frame or hanger. This operation of coiling the boxv strapping is accomplished in any ends composing the side member 5, after which the ends of said tongues are bent in opposite directions as at 12, thus completing the operation of placing the coiled strapping within the frame and securing the several parts in proper operative relation to each other. The tongues 11 serve two purposes, first, they secure the free ends of the sheet metal band forming the frame in fixed or predetermined relationto each other so that all the parts of the frame or hanger are attached in a simple and strong manner, and, second, said tongues 11 form a stationary journal upon which the spool is free to turn. The frame or hanger is shown as having apertures 13 near the looped end a through which apertures is adapted to pass a wire, hook or any other suitable device for the purpose of suspending the entire reel in a manner forthe operator to draw the strapping from the spool.

The construction of Figs. 6, T and 8 embodies the generic features of the sheet metal frame and the sheet metal spool, but the particular means for mounting the spool and for retaining in proper relation the free ends of the metal composing the frame are modified in the following particulars. Instead of providing tongues on one side member of the frame, the spool B is provided at its middle with two pairs of tongues 14, 15 composed of metal struck up from the disk 2). The tongues 14 are bent from the disk so as to extend in one direction therefrom, whereas the tongues 15 are bent to extend in an opposite direction from the d sk. The cheek piece 4 on side member 1 of the frame is provided with a circular aperture 16, whereas the free ends of the side member 5 composing the other cheek piece 8 are provided with registering apertures. The spool, after the strap shall have been coiled thereon, is positioned within the frame so that the tongues 14 extend through the aperture 16 in cheek piece 4, whereas the tongues 15 extend through the apertures in the free overlapping ends of the side member 5, after which tongues 14 are bent to overlap the edges of the aperture 16, and tongues 15 are bent to overlap the edges of the openings in the overlapping end portions of the side member 5. By bending the tongues 14, 15, the spool is connected with the cheek pieces and the free ends composing the member 5 are retained in predetermined relation to each other. The tcngues 14, 15 of the spool are free to turn within the circular apertures provided in the cheek pieces 4, 8 of the respective side members composing the frame, and thus the spool is rotatably supported within said frame.

Instead of providing means integral with the frame or the spool for supporting said spool rotatably within said frame, I may use a rivet C, as shown in Figs. 9 to 13, inclusive. The frame is provided with openings 18 in the respective cheek pieces 4, 8,

and the disk of the spool is provided with an aperture 12 the latter being in alinement with the apertures 18. The rivet 0 passes through the alined apertures in the disk of the spool and in the cheek pieces of the frame, as shown in Fig. 10, and the ends of said rivet are flanged or headed so that one head will engage with one cheek piece and the other head will engage with the other cheek piece. The rivet is preferably tubular to facilitate the operation of upsetting the ends thereof and this rivet serves the purpose of a journal for rotatably supporting the spool within the frame.

From the foregoing description it will be apparent that I have provided a reel or hanger, the frame and the spool of which are composed of sheet metal, whereby each part may be easily, rapidly and economically manufactured. The coil of strapping may be rapidly wound upon the spool, and said spool easily placed in position, after which the several parts are secured together by a simple and eificient fastening means. The spool being free to rotate within the frame, the strapping may be drawn from the spool as required during the operation of applying the strap to boxes, packing cases, etc. The several parts of the hanger are secured together firmly so that the frame will not become accidentally separated or opened.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is' 1.
